The optimum reaction conditions for the preparation of the precipitated calcium carbonate of an average particle size of 0.05mc in diameter was set in which the Box-Wilson Plan was applied. The reaction conditions are as follows: 1.concentration of milk of lime; 6.56% w/w 2.temperature; 14.24oC 3.velocity of carbon dioxide introducing; 1.95l/min The crystal form was found that of calcite in X-ray diffraction analysis. The particle size was determined by the sedimentation volume measurement. The shape was identified by the electron micro-diffraction pattern and the electron microscopic photographs.
